APPLICATIONS
%
The K78xxM-1000 series high efficiency
switching regulators are ideally suited to replace
78xx linear regulators and are pin compatible.
The efficiency of up to 93% means that very little
energy is wasted as heat so there is no need for
any heatsinks with their additional space and
mounting costs.
